Specificaton of Letters Patent.

To all whom it may cncem Be it known that I, KROLY PAP, a subject of theKing of Hungary, and resident of Kolozsvr, Austria-Hungary, have inwater-gage, and another defect of most of the devices consists in thatthe stokers or firemen are liable to be injured by the es- ,caping steamand hot water in *case the glass of the water-gage is broken.

It is one of the objects of the present invention to provide a simpleand inexpensve water-gage, by means of which the level of the water inthe boiler may be observed within a substantial distance from theboiler, and furtherrnore to produce an automatic safety shut-oflwhereby,as 'soon as the glass of the gage is broken, the supply of steam andwater is automatically shut off therefrom. i

With these and other objects in view, which will'more fully appear asthe nature of the invention is better understood, the same consists inthe combination, arrangement and Construction of parts hereinafter fullydescribed, pointed out in the appended claim and illustrated in theaccompanying drawings, it being understood that many changes nay be madein the size and proportion of the several parts and minor details ofconstruction within the scope of the appended claim without departingfrom the spirit or sacrificing any of the advantages of the nvention.

One of the many possible enbodiments of the invention is llustrated inthe accompanying drawings, in which zx Figure 1 is a verticallongitudinal section taken through a safety water-gage constructed inaccordance with the present invention; and Fig. 2 is a front elevationof the dial of the same.

In the drawings, the numeral 1 indicates the head of a boiler, and thenumeral 6 a closed receptacle, which communicates by means of pipes 2and 3 with the interior of the boiler. The pipe 2 leads to the steamspace and the pipe 3 to `the water space of i theboiler, 'Intothesepipes are inserted valves i and 5, respectively, hereinafter to bedescribed.

guides ll, 11 upon the interior surface of the casing 6. The upper endof the casing 6 is provided with acylindrical enlargement 1 1, which is:provided upon its outer face with a graduated dial 15. `he upper end of'the extension 9 of the float isprovided with a rack 10, the teeth ofwhich are' adapted to mesh with'those of thetgear segment 12, which iskeyed or otherwise attached to a spindle 13, the latter being os-.

cillatably arranged in the front wall of the enlargenent 14 andprojecting therethrough. To the spindle 13 is attached'a hand 16,pointing to the graduations'of the dial 15.

The casing 6 is provided in its front wall 17 with a window, which isclosed by two` panes of glass 18 and 19, or other suitabletransparentmaterial, said window-panes being, arranged at a substantial distancefrom each other. A pipe 21 leads from the space between the twowindow-panes 18 and 19 to the head of a steam cylinder 22, which latteris attached to the boiler head or to any suitable support. VVithin thecylinder 22 is reciprocably arranged a piston 23, the piston rod 24 ofwhich is pivoted to a connecting rod 25, the latter being in a similar'nanner attached to a lever 27, which is keyed or otherwise attached tothe plug' of the valve 4. A link 26, pivoted to the connecting rod 25,is in a similar manner secured to a lever 28, which is rigdly connectedwith the plug of the Valve 5.

The operation of the device is as follows: As the level of the water inthe boiler vafor 'a purpose, Within the re ceptacle 6 is arranged a hollow, preferably,` nietallic fioat 7 the' upwardly projecting extension9 of which is slidably arranged in' Patented Sept), 1913.

ries, the fioat 7 will accordingly rise or fall,

and actuate thereby the hand 16 -above described. The level of the waterin the boiler can thus be observed from a distant point by exarniningthe positions of the hand 16. [f for some reason the inner one of thewindow-panes, that is the pane 18, should be broken, steam will escapethrough the pipe 21 into the cylinder 22, act upon the pisten 23 andthereby shut off automatically steam and water fromthe casing 6.

transparent panes which are arranged at a distance from each other, of ahollow fioat in said receptacle, a graduated dial, a hand oscillatablymounted upon said receptacle pointing to the graduations-of the saiddial,

. y coperating means upon said fioat and said hand for act-uatng thelatter upon the rising and falling ofthe fioat in said recep-- betweenthe boiler and said closed receptacle, a steam cylinder, a pstontherein, a

'connection between said piston and said valves, and a steam pipeleading from the space between said two window-panes to said cylinder.
